This is an incorrect usage of these elements. The probe needs to be next to
an audio sink (e.g. before alsasink/pulsesink). The probe monitors what
goes to your loud speaker so it can be removed from the stream coming from
your microphone (alsasrc). Some explanation can be found here.

P.s. alsasink introduce 200ms of latency by default, which is too much for
echo cancellation. Consider reducing the buffer-time property).
